That yeasty water is what you put directly into your fermenter with what ever juice you want to ferment. Just make sure there aren't any preservatives in it.
Make sure the yeast you're starting is in a warm part of the house, it may take a week to get a good effervescing just open the bottles to vent probably daily, being careful to not contaminate.

You can use a gallon jug with a balloon on it for a fermenter if you don't have an airlock, or just a piece of tubing going to a jar of water from whatever you can come up with for a fermenter. Just make sure everything is air tight and clean.
